After a look back at philosophy of science in the 1930s- 1950s, I turn to discuss the current potential for returning to a more engaged philosophy of science. Although philosophers of science have much to offer scientists and the pub- lic, I am skeptical that much can be gained by philosophers importing off-the-shelf discussions from philosophy of science to science and society. Such efforts will likely look like efforts to do applied ethics by merely applying ethical theories to particular contexts and problems. While some insight can be gained by these kinds of endeavors, the most interesting and pressing problems for the actual practitioners and users of science are rarely addressed. Instead, I recommend that philosophers of science engage seriously and regularly with scientists and/or the users of science in order to gain an understanding of the conceptual issues on the ground. From such engagement, flaws in the traditional philosophical frameworks, and how such flaws can be remedied, become apparent. Serious engagement with the contexts of science thus provides the most fruit for philosophy of science per se and for the practitioners whom the philos- ophers aim to assist. And if one focuses on contexts where science has its most social relevance, these efforts can help to provide the thing that philosophy of science now lacks: a full-bodied philosophy of science in society.

3 1 8 Synthese (20 1 0) 1 77:3 1 7-335 1 Introduction In this paper, I will lay out a general approach for doing socially relevant philosophy of science derived from my own experience in attempting to do such work. I have found it to be a very productive approach, not only for providing potentially useful insights to science practitioners, but also for thinking about and challenging standard positions within philosophy of science. Contrary to typical views of applied work, doing this kind of work has not involved a straightforward application of ready-made philoso- phy of science to a socially relevant context. Standard philosophical positions have not proven adequate for the contexts of use in which I am interested. Instead, it has involved understanding the conceptual terrain in a socially relevant context ("on the ground," as it were) and thinking through the norms involved, employing distinctly philosophical techniques of conceptual analysis. Because the normative considerations that arise from the context require refinements or revisions of philosophical views, the concep- tual work in the context of interest generates the particularly productive character of this approach. Two caveats are needed before I begin. The first is about what I mean by socially relevant work, and the second about what my arguments imply for the trajectory of philosophy of science. By socially relevant work, I mean to focus attention on those aspects of science that are of particular relevance to society. I am, of course, not the first to do this. I will note below some of the growing body of work with this character. Doing socially relevant work can be distinct from taking a political approach to philosophy of sci- ence. In the approach I describe here, one need not have a particular political agenda driving socially relevant work. The only political commitment underlying the work I describe below is to general democratic principles, a minimal stance. Additional particular political commitments have driven some philosophers of science, such as feminist concerns in feminist philosophy of science or socialism in the work of Otto Neurath. So political concerns can drive socially relevant philosophical work, but it need not. Social relevancy can occur through looking at issues that arise in socially relevant science, and thus that may cut across particular political agendas. Because of the importance of public discourse and accountability in democracies, a commitment to democracy generates an impulse for as much clarity and transparency as one can muster, an impulse in line with most philosophers' instincts. But such clarity can serve a range of political commitments when at work on particular cases, intentionally or not. Thus, the socially relevant work I wish to promote need not be politically charged or directed. And while it may have interesting political implications, it need not be done with expressly political motivations. In describing how socially relevant philosophy of science can be done and how it can be both productive for the field of philosophy of science and helpful to the practitioners and users of science, I do not mean to suggest that this is the only type of philosophy of science one should pursue. Such a view would impoverish the field, reducing the kind of disciplinary conversation that provides coherency. However, room should be made for socially relevant work, without prejudice or penalty. And as issues arise that fall outside the traditional boundaries of philosophy of science (which as we shall see is not a very long tradition), such work should challenge the philosophy of science to 4y SpringerThis content downloaded from 175.111.91.124 on Fri, 27 Jan 2017 04:55:48 UTCAll use subject to http://about.jstor.org/terms

Of course, to convince a skeptic. Once this approach mine whether in fact it proves its merit. whether others will use it with fruitful gathered. Is such an effort worth it? One might worry whether and why practitioners and users of science will welcome philosophers of science to debates over how to use science in policy, the proper public role for scientists, and how to direct science funding. I think philosophers have much to offer practitioners - philosophers of science bring into these contexts a valuable skill set, namely capabilities to think clearly about sci- ence, about the relationships between evidence and theory, and about the assumptions and inferences made in science. Philosophers can use these skills to pinpoint, articu- late, and address difficult conceptual issues. Even if the standard philosophical views provide little direct assistance, utilizing these skills in various contexts can provide an invaluable service to scientists and the public. Engaging in these messy and complex contexts can also provide invaluable insights for philosophy of science. By paying close attention to the particular difficulties a sci- entific community and/or its public faces, rather than presuming the issues on the ground will fit into standard philosophy of science topics, philosophers of science can gain new perspectives on traditional debates. It is in the examination of and engage- ment with scientific practice in society that philosophers of science can test their well developed theories, see their pitfalls, and develop new approaches to old problems. The crucible of application forces clarity and adds needed complexity. Indeed, many philosophers of science whose work focuses on a particular science (neuroscience, physics, evolutionary biology, chemistry, ecology) already know how useful it is to examine actual scientific practice. By engaging with these issues on the ground, not just in the special disciplines but also in the contexts of science engaged with society, and with an openness to challenging standard philosophy of science views, fruitful interaction can flourish.

Laudan distinguishes epistemic nal consistency (which are needed to the cognitive concerns focused on fruitfulness. the minimal standards of empirical should not be considered a live option. the preferences of the scientists, according tists at the policy interface to consider indicative of predictive accuracy makes The value-free ideal also blocks crucial considerations of how much evidence should be considered sufficient. In deciding this, scientists should be concerned with the amount of uncertainty that is acceptable for any given decision, which can and should depend on the consequences of error. Those consequences include the potential construction of faulty policy based on the possibly erroneous scientific claims, and thus include social and ethical consequences (Douglas 2000, 2009a, Chap. 5). These are considerations that scientists working on policy-relevant science should be weigh- ing openly. Thus, in addition to attempting to select the most reliable interpretation of available data, there are important considerations pertaining to the consequences of choosing a model incorrectly - which sorts of errors are more acceptable, false positives or false negatives? Answering such a question in the science policy context requires the consideration of social and ethical values, the very values vanquished by the value-free ideal. The value-free ideal is of no help to such scientists, demanding that they focus on values of little relevance and that they ignore values of central importance. In examining the science-policy context more closely, and listening to the practi- tioners grapple with their concerns, the flaws of the value- free ideal become apparent. There is no rational reason why social and ethical values should be ignored when deciding how much evidence is sufficient for a claim, and there are moral responsibil- ity reasons for why they should be considered (Douglas 2003, 2007, 2009a, Chap. 4). Rejecting the value-free ideal should allow for more open discussion of how burdens of proof and levels of sufficient evidence should be set for science in policy debates. It also opens the door to greater democratization of the science advising process (Douglas 2005; Elliott 2008; Guston 2004). If social and ethical values are needed to weigh potential consequences of error, the affected publics can and should have input on the values scientists should use in this weighing, be it through mechanisms such as consensus conferences which allow for informed deliberation on value ques- tions or participatory research models where members of the public work closely with scientists to develop needed knowledge. However, some of the philosophical worries about the possibility of values running roughshod over evidence remain. There is a need to define a new ideal, one that both <ö SpringerThis content downloaded from 175.111.91.124 on Fri, 27 Jan 2017 04:55:48 UTCAll use subject to http://about.jstor.org/terms
Synthese (2010) 177:317-335 327 protects the integrity of science and society. This is clearly work for philosophers Taking up this challenge, I have developed in scientific reasoning. In doing so, I reasoning rather than the kinds of value roles can be articulated, a direct role are a primary reason for a choice. They role values play in shaping many of values are a reason not to proceed. If a reason to proceed. At some locations problematic, and indeed may be required. or which methodologies are ethically values direct our choices. However, at role is deeply problematic. When deciding should be a reason in itself for such a choice. Nor should values direct our choices in how to characterize evidence. Values in the direct role at these locations instantiate the concern about wishing making it so, or about values having the same (or even more) weight as the available evidence. The pernicious uses of values in science can be traced to the use of values (whether cognitive or ethical) in a direct role when assessing theories. But the direct role is not the only role values can play in reasoning. The indirect role is also important, although values constrained to this role are not as determinative of the decision being made. In the indirect role, values only have import for assessing the sufficiency of evidence, for assessing how serious lingering uncertainties are. As there is always an inductive gap between evidence and theory, there is always some uncertainty to weigh. And in weighing this uncertainty both cognitive and ethical val- ues can be useful, depending on the context. Ethical values can help us assess our concerns over the consequences of error, of making an incorrect interpretative choice. Cognitive values can help us assess what the likelihood is that an error will be discov- ered sooner rather than later. Recall that theories which instantiate cognitive values like simplicity, scope, and explanatory power are at their core reflecting the potential fruitfulness of the theory - whether it is easier to work with, to develop, and to test further. As a result, the needed refinements (or wholesale rejections) of such theories are more likely to be apparent sooner. Thus, in theory assessment, the indirect role is the proper avenue for both cognitive and ethical values. And it is a weaker role than a direct role, protective of scientific integrity. In the indirect role, the values (ethical or cognitive) only have import through uncertainty, not through the direct assessment of the theory. The more one is able to reduce uncertainty, the stronger the evidential case, the less important the values are. Because values are constrained to the indirect role only at the heart of science, we could call this the constrained- value ideal. With this understanding of values in science, we can both clarify what the role for values in science should be (a central philosophical question) and clarify how scien- tists should proceed in their work at the science-policy interface. Values can saturate science, but still should not compete with evidence. Scientists can legitimately use social and ethical values to assess how much evidence should be considered sufficient for a claim, but with the value-free ideal replaced with the constrained-value ideal ^ SpringerThis content downloaded from 175.111.91.124 on Fri, 27 Jan 2017 04:55:48 UTCAll use subject to http://about.jstor.org/terms

Epidemiolog- ical studies must study humans in real contexts with no ready-made controls to manage confounding factors. Epidemiologists must attempt to construct control groups, aware that confounders are nearly impossible to eliminate completely. In addition, actual exposure assessments usually must be indirect, relying upon historical accounts, per- sonal memory, or other surrogates rather than direct measurement.

Working with actual scientific practice is a not new technique for philosophers of science. What is new here is the engagement with less "traditional" (if tradition is traced back only to the early 1960s) contexts of scientific practice. Concern with, for example, the use of science in policy-making, the development of policy for science, the understanding of science in education, the public role of scientists, or the proper ethical restrictions on scientific practice, will not only broaden philosophy of science, but improve its conceptualization of science. These kinds of activity are an integral part of the scientific enterprise - even a cursory look at the amount of money dedicated to "applied science" or the journal space devoted to science relevant to public policy indicates what a profound part of the scientific world such practices compose. As such, science is not just an epistemic enterprise.
